SAMUEL c. YEAToN, on NEW-YORK, N. Y.

'TNNERFSEALED RECEPTACEE.

To all 'whom t may] concern:

Be itknown thatl, SAMUEL C. YEATON, u a citizen of the "United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certaink new' and useful Improvements in Inner-Sealed Receptacles, of which v the following is a specification.

This invention relates to inner sealed receptacles, that is to' say, receptacles wherein the seal is contained in the interior thereof, as for instance,'inthe type of glass bottles wherein the seal is contained in the interior of the neck as distinguished from the capped or crownsealed bottles" wherein the seal fits over the top and around the outsidev of the mouth-ofthebottle. n

More particularly, this invention relates y to that class .ofinner sealed receptacles in which the seals may be appliedy and removed without the use of implements.

The'object of the invention is the devising I of an innerseal ofthe above type, which by its own resiliency may be brought to the locking and unlockingy positions without permanently distorting` it, thereby permit# ting of its repeated use.

"Referring to thel drawings, Figure l is a v fragmental sectional'view of a bottle neck v,

and a seal about to be inserted therein. Fig. 2 is a fragmental sectional view of a. bottle neck and a seal inserted therein in sealing position.' Fig. 3 vis a plan view of L y.mental sectional view of a bottle neck and blank seals. Figa t isja fragmental sectional view of a bottle neck and a seal inserted therein but in a position to be ifemoved from the neck, and` Fig. is a frag# niodifiedform Vof seal inserted therein i sealing position.

The bottle neck y1 is provided with ay seat 2 formed within the interior thereof and anr abutment 3 also formed within the interior abovethe seat. The usual pliable gasket a -of cork, rubber, or other suitable material is placed upon the seat as shown in Figs. 1 and 2. There is nothing novel about the use of these gaskets and are not shown in Figs.

l and 5 but it is understood that they arel preferablyused where liquids are contained within the receptacles but may not be needed in other instances, as for instance, where the receptacle contains solid material.

The seal is stamped from suitably resilient sheet metal and comprises a body portion 4; of preferably circular formation and a plu Specification of Letters Patent. I

iality of lockingy fingers piojecting from I' the body portion.` The lingers are turned upwardly as shown in Figs. l and 2 and one or more of them may be providedfwith ex-y tensions 6 forthe appear. Fig. 3 ner of stamping the. disks. Here two extended fingers ga're shown, the extended portions being taken from the waste portion of metal l'between three k7adjacent seals. The body 'of the seal is formed witha ksuitable upward bulge, as shown in Figs. l' andv 2.

Where the gasket a is'usedit may be first inserted on the seat 2 or it may be permanently secured to thek seal'in Aany suitable The portionffof the neck p purpose as will presently shows an economical man` land well yknown manner. .The sealis in` fingers 5 are obliged to crowd ,inwardly somewhat vtok pass this portion rand when within the neck spring outwardly to normal or nearly normal positions, thereby locking themselves 'beneath the abutment 3. Pressoy sure may be applied' to the body ofthe seal, I i

to producek a squeeze yupon vthe. gasket andl vthe fingers may be4 forced into locking position if found necessary when' a very tight closure is desired, yas in the case'of bottles containing liquids under pressure. The stock forming theV abutment 3 may be rounded as shown or may" convergevupwardly so that 'i the farther the fingers 'are forced outwardly the more pressure they will exert vupon `the seat. This alsopermits the fingers toy'assume slightly ydifferent relative positions' to`r 'f adapt themselves f to slight 'irregularities y of formation `of the bottle or seal. This makes it feasible in many `casesto form a tight seal without the use of a sealing machine.' To

remove the seal, kthe biilged body portion is forced downward. This tends to decrease the angularity` of the body portion and if the fingers were held rigid would change the the angularity between them and the body icov portion. The metal is however sufficiently A rigid at the bend between the body portiony and' fingers to prevent a change of angularity .between them with the result that'as the inclination of the bulge of the body portion changes it swings the lingers inwardly correspondingly until they are free from the abutment. The extensions Gare bent over as shown in Figs. l and '2 and may be gripped' to piek the seal cut of the neck when the body portion has been suitably depressed.

Pressure actuated bulged portions upon seals are not, r, broadly considered, new. They are found in the U. S. Letters Patent to Flanigan, Number 11,629, Mulvaney, Number `800,867 and Kaufman, Number 851,424. These patents relate -to crown seals, in which different principles are involved requiring different constructions than could be utilized with inner seals.

` There ysufficient pressure is applied to the bulged portion toy force it past a straight or plane position it can be made to assume a reverse curvature. Thiswill result in holding the lingers in their unlocked positions.`

But to lockthe bottle the bulge will have to be forced back 'to its `first or 'upwardly bulged position. lhen it Yis desired to prevent the bulged portion from passing or quite reachingt-he plane, the lingers are suitably spaced so rthat they will come together as shown in Fig. 4 before the bulged portion 4 reaches the plane but not until the fingers 5 have moved free from'the abutment. The. fingers in this closed posi.- tion resist the further depression of the bulged portion. l

Fig-.v 5 shows another way of preventing the bulged portion from reaching the plane. Here a disk Tis placed beneath the seal. The diskis given a less curvature than the bnlged portion 4 so that when the bulged portion is depressed it will strike the disk butnot until the fingers have vmc'wed free from the abutment.`

This .sealis'wellr adapted for such wide v` mouthed bottles as theordinary milk bottle.V lt has the advantage of having the bulged portion protected within the neck of the bottle so that the bottles may be placed one upon the other without affecting lthe seal.

In the case of the capr variety of seal above referred to, the bulge extends above the top of the bottle and if subjected to a4 blow or suliicieut lpressure by ,bottles or other weights placed upon it,'would depress,

.whichmight result in opening the seal. It

is (possible vto make part of theingers wider, or stiffe'ryor spread farther outwardly than the remainder, for instance, the fingers on the right in Fig. 1 may be thusreinforced.

This will produce a relative Weakness of lthe fingers on the left-hand side. Then the bulged portion is depressed the weaker fingers move first and the seal may be freed by raising that side from the bottle.
